The above diagram shows a small sample network with the stack of Catalyst 3750s providing inter−VLANrouting between the various segments. The following are the three user defined VLANs: VLAN 2 − user VLAN • VLAN 3 − server VLAN • VLAN 10 − management VLAN • The default gateway configured on each ser...

Page 6 - Configurations; This document uses the configurations shown below.

VLAN 1 is not used for management. All ports in Catalyst switches default to VLAN 1, and anydevices connected to non−configured ports will be in VLAN 1. This may cause potential issues forthe management of switches, as explained above. • A Layer 3 (L3) (routed) port is used to connect to the default...
